    Default Re: Is this a transducer? Can I re-use it?

    The constant TLC will be worth it. Good luck with everything.

    Joining transducer cables is also possible without major issues - it is only 150kHz not radio frequency.
    Modern echo sounders work at anything from 80khz to 200khz or more. Expect significant loss of sensitivity if 'detuning' it. Or not, if you are very lucky! Mine is dual frequency (80khz and I think 220khz which allows greater depth or greater accuracy. Joining cables is not rocket science, but what sort of shape are the conductors in after many years exposed to salt damp atmosphere in the bilges?. Ok if it was tinned, but otherwise it could be quite difficult to get a good connection. Then what sort of condition is the crystal in anyway? Yes it is /should be fully sealed, but we all know how damp can penetrate older gear. Re-using the hole is the simpler option imho, and even they are not standard.... :-)
